Lipo battery cut off Answered

I'm using a couple of Lipo batteries to power a speaker on a trailer, I bought 2 low voltage alarms that plug into the balance cables but upon testing I found it to be unlikely that I'll hear them over the speaker. So would it be possible to modify the alarms so that they activate some kind of cut off device attached to the power cable instead? Each battery is 4s 10000mah.

I'm not sure what you want to do (I'm not very good at English, maybe its why) . Do you want alarms to activate something (speaker for example) or what do you want? Can you explain it better?

1. Your Lipo should already have a protection circuit on it or on the PCB for charge and discharge protection.

2. Change the alarm output for a flashing LED.

3. Pu the audio alarm in a tin can to amplify the sound.

i'm hoping that the alarms can be modified in some way so that instead of making a noise i probably won't hear they cut off the power from the batteries instead. is there perhaps some kind of electronic switch that could be set up to unlatch instead of setting an alarm off?

A strobe maybe? Or a relay to a louder alarm/siren?
